摘要：
The cluster-galaxy cross-correlation and the average infall velocity around cluster for the tilted CDM models, the hot-cold mixed dark matter models (MDM) and theA CDM models are calculated. And it is found that the prediction of the cluster-galaxy cross-correlation of theA CDM models with ΩA=0.9, ΩC=0.1,h=1,b = 1 or 2 is much higher than that of observation for the radius larger than 10 h−1 Mpc (H0 = 100 h.kms−1Mpc−1), and the other models are compatible with the observation on the scale of (3–20) h− Mpc. The results can be used to compare with new observations to restrict the nature of the dark matter and the biasing factor.
